Comparison: Hormonal Pathways and Hair Follicle Impact
To make this clearer, let's look at a side-by-side comparison. This visual breakdown really highlights the fundamental differences in how these compounds interact with the body's systems related to hair. MK-677 (Ibutamoren) Ghrelin Receptor Agonist; GH Secreta

- To make this clearer, let's look at a side-by-side comparison. This visual breakdown really highlights the fundamental differences in how these compounds interact with the body's systems related to hair.
- MK-677 (Ibutamoren)
- Ghrelin Receptor Agonist; GH Secretagogue
- None / Negligible
- Significant Increase
- Neutral to Potentially Positive (via IGF-1)
- Testosterone
- Binds to Androgen Receptors; Precursor to DHT
- Directly Increases
- Minor Increase
- Negative (via DHT-induced miniaturization)
- Finasteride
- 5-alpha Reductase Inhibitor
- Significant Decrease
- Positive (by blocking DHT formation)
- As you can see, MK-677 operates in a completely different universe than the androgens that cause hair loss and the drugs used to treat it. Its primary impact is on the GH/IGF-1 axis, which is generally considered favorable for hair growth.
